The terminal epoxy polyether silicone oil is a double-active silicone epoxy resin intermediate having a polysiloxane segment with an epoxy group and a polyoxyethylene ether segment at both ends and a linear polysiloxane segment in the middle. Because it has an epoxy group, it can be cured with an amine-based curing agent, and is widely used as an additive for epoxy resin. It is also an important intermediate for the synthesis of block silicone oil by replacing the epoxy resin.
